IMPROVEMENT IN CAR-VENTILA-TORS.

Specification forming part of Letters Patent No. 171,61 l, datedDecember 28, 1875 application filed December 1, 187 5.

To all whom it may concern:

Be it known that I, GEORGE F. GoDLEY, of Philadelphia, in the coun'ty ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Gar- Ventilators; and do hereby declare the following to be a full, clear, and exact descrip-I tion of the invention,such as will enable othl ers skilled in the art to which it pertains toVmake and use it, reference being had to the accompanying drawings,which form part of this specification, in which- Figure l is alongitudinal Vertical section of a car, showing the application of myinvention. Fig. 2 is a perspective of the revolving elbow. Fig. 3 is aperspective of a modication. Fig. 4: is a plan of the revolving elbow.Figs. 5 and 6 are broken elevations, showing my invention applied tofreight and fruit cars.

My improvements have for their object to provide meansv for morethoroughly and effrciently Ventilating passenger and other railway carsthan has been heretofore possible.

My invention consists in the peculiar con-- struction, combination, andarrangement of parts hereinafter more fully described, having referenceparticularly to the provision of a swiveled elbow-pi pe, intended to beplaced, by preference, underneath the door of the car, connecting withthe interior of the latter by means of a registered opening, andgenerally so arranged that the forward motion of the car will cause saidelbow to swing around in such manner that its exit-opening will betoward the rear of the train, the suction of the latter having theeffect of drawing the air out ofthe car through said elbow.

Referring to the accompanying drawing, A designates a passenger-car; B,the floor, and C the roof, of the same. D D designate openings in thebottom of the car, located at suitable intervals in any desiredposition, either inthe aisles, or underneath or between the seats or atthe sides. These openings are provided with registers d, below whichthey receive the collars e of an elbow-pipe, E, said elbow by this meansbeing swiveled, so as to turn freely in any direction upon its verticalaxis. The moair out ofthe interior of the car, as indicated by thearrows y.

If desired, the exit-opening of the pipes Ey may be closed by valves e',which will remain closed when the train is at a state of rest, but willautomatically fly open when in motion.

Instead of a swiveled elbow a single pipe or a series of pipes, two ormore, as shown at F in Fig. 3, having outwardly-opening valvesj f ateach end, may be employed. In either case fresh air may be supplied tothe cars through a perforated tube, Gr; arranged below the roof, andcommunicating', by branches g, with exterior short pipes II, havinginward-- ly-opening valves h h'.

For grain, fruit, or other freight cars, the

registers d may be dispensed with, and a foraminated tube or trunk, I,substituted therefor, said trunk being combined either with the elbow Eor pipe F.

The elbow E may be advantageously combined with the exit-pipe of acar-urinal, K, and' by producing a forcible air-current through the samewill have the effect of carrying o the ammoniac-al and other obnoxiousvapors usually incident to such fixtures.

What I claim as my invention is-" l. In combination with a car, aswiveled elbow-pipe depending from the door, as shown and described,whereby, through the suction produced by a moving train, said elbow-pipewill receive and expel the 'vitiated air from the interior of the car,substantially as set forth.

2. In combination with the car-floor, having an opening'or recess, D,the swiveled el' bow-pipe E, having the collar or ange e, substantiallyas described and shown.

3. In combination with the swiveled elbowpipe E, applied substantiallyas shown, an automatically .opening and closing valve, e', substantiallyas shown and described.

4. In combination with an air-pipe placed below the door of a car, anautomatically open.

ing `and elosingvelve or \v'ai`ves,isubstaintinlly as shownanddescribed.

5. In combination with a. perforated pipe, Gr, for admitting air to thecar in theupper section, a. pipe or tube for drawing off the vitatedatmosphere through the floor or sides@` substantially as shown anddescribed# In testimony that I claim the foregoing hztvehereunto set myhond this 27th day of November, 1875. GEORGE F. GrODLEYA.`
